Objectives. Infants with slight/mild or late-onset hearing impairment might be missed in universal newborn hearing screening (UNHS). We identified the mutation hot spot of common deaf gene in the newborns in Jinan area population by screening the mutation spot with neonate cord blood, in order to make clear whether the neonate cord blood for screening is feasible. Methods. Six hundred and forty-six newborns were subjected to both UNHS and genetic screening for deafness by using neonate cord blood. The newborn genetic screening targeted four deafness-associated genes, which were commonly found in the Chinese population including gap junction beta-2 protein (GJB2), gap junction beta-3 protein (GJB3), solute carrier family 26 member 4 (SLC26A4), and mtDNA 12S rRNA. The most common 20 spot mutations in 4 deaf genes were detected by MassARRAY iPLEX platform and mitochondrial 12S rRNA A1555G and C1494T mutations were sequenced using Sanger sequencing. Results. Among the 646 newborns, 635 cases passed the UNHS and the other 11 cases (1.7%) did not. Of the 11 failures, two cases were found to carry homozygous GJB2 p.R143W pathogenic mutation, one case was found to have heterozygous GJB2 235delC mutation, and another one case carried heterozygous GJB3 p.R180X pathogenic mutation. Six hundred and thirty-five babies passed the newborn hearing screening, in which 25 babies were identified to carry pathogenic mutations, including 12 heterozygotes (1.9%) for GJB2 235delC, eight heterozygotes (1.3%) for SLC26A4 IVS7-2A>G, one heterozygote (0.2%) for p.R409H, two homozygotes (0.3%) for m.1494C>T, and two homozygotes (0.3%) for m.1555A>G. Conclusion. Newborn genetic screening through the umbilical cord blood for common deafness-associated mutations may identify carriers sensitive to aminoglycoside antibiotic, and can effectively prevent or delay hearing loss occurs.
Performing Side-Effects in Restricted AND/OR Parallel Execution model of Prolog
Liu, Zhi Long,Hu, Shou Ren 대한전자공학회 1992 HICEC:Harbin International Conference on Electroni Vol.1 No.1
Logic programming has gained its popularity in symbolic processing. A question that naturally arises is how to execute standard sequential prolog programs with side-effects in parallel. The problems of performing side-effects in AND parallel systems and in OR parallel systems have been considered elsewhere. This paper makes an inquiry into how to control side-effects in an Restricted AND/OR parallel execution model. The synchronization blocks are added in compiling time. The extension of the Warren abstract instruction is given out. Finally, our future work is given out.
Long noncoding RNA atlas of the inflammation caused by asthma in mice

There is little evidence regarding the roles oflong noncoding RNAs (lncRNAs) in inflammation caused byasthma. In this study, we successfully generated an asthmamouse model that was induced by ovalbumin (OVA). Theeffects of dexamethasone (Dex) treatment on lung tissuewere investigated using pathological and biochemicalmethods, including Diff-Quik staining, enzyme-linkedimmunosorbent assay (ELISA), hematoxylin–eosin (H&E)staining, and western blotting (WB). The inflammation waseffectively relieved with Dex treatment. High-throughputsequencing revealed that a total of 1490 lncRNAs were detected in lung tissue samples. Differential expressionanalysis revealed that the Dex group had 20 upregulatedand 15 downregulated lncRNAs compared with those inthe Model group. Moreover, nine differentially expressedand inflammation-related lncRNAs were verified by quantitativereal-time reverse transcription polymerase chainreaction (qRT-PCR). Furthermore, the regulation networksof these nine lncRNAs, their potential binding microRNA(miRNAs), and the putative target genes showed that theselncRNAs play important roles in the nuclear factor kappalight-chain-enhancer of activated B cells (NF-κB) signalingpathway. We further identified the expression levels of threepotential binding miRNAs by qRT-PCR. The results of thisstudy contribute to a better understanding of the functionsof lncRNAs in inflammation caused by asthma.

Background/Aims: Colorectal cancer is the third leading incidence of malignant tumour in the world and the incidence of colorectal cancer has steadily been increasing in Asia in recently years. The aim of our study is to determine the basic demographic features of patients with colorectal cancer and the anatomic distribution and characteristics of the tumour in Guangdong population. Methods: A review of patients from 1990 to 2004 at five hospitals was conducted, including Peal Triangle Area in Guangdong (Nanfang Hospital and Huizhou Central People`s Hospital), North area of Guangdong (Shaoguan North-Guangdong People`s Hospital), West area of Guangdong (Affiliated Hospital Guangdong Medical Institute) and East area of Guangdong (Meizhou People`s Hospital). Results: Analysis was carried out on 6,501 patents, only 6,488 cases provided age. The age ranged from 5 years old to 91 years old and the mean age of 6,488 cases is 59. 5.2% (340/6,488) of the patients was young CRC patients. The peak incidence was between the ages 61 and 70 years old (29.5%). The mean age increases from 55 years old (1990-1992) to 61 years old (2002-2004) and the proportion of young CRC patients descends from 7.1% to 3.5%. The make to female ratio is 1.5:1 and the ratio increased with age increasing. Of 6,501 lesions, 3,423 (52.7%) were located in rectum and 3,078 (47.3%) in colon, the ratio of rectum cancer to colon cancer is 1.1:1. The proportion of rectum cancer decreased significantly from 74.5% (1990-1992) to 64.9% (2002-2004) and that of the right sides colon cancer increased from 25.5% to 35.1%. In four different areas, the mean age of CRC increasing and East area of Guangdong ranked the fist. There was no significant difference in the ratio of male to female. Conclusions: The demography of colorectal cancer in Guangdong is different from before and further study should be pursued to find the reason.
Cancer Registration in the Peoples Republic of China
Wei, Kuang-Rong,Chen, Wan-Qing,Zhang, Si-Wei,Liang, Zhi-Heng,Zheng, Rong-Shou,Ou, Zhi-Xiong Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.8
The current situation of cancer registration in China was systematically reviewed. So far, cancer registration in China has been making a great progress in the following aspects: the number of cancer registries and covered population have increased dramatically; a registration network has been established and completed gradually; regulations and rules improved remarkably; more attention is being paid by every level of government; a lot of registration software has been created and financial support ensured. However, we are still facing some problems and challenges, such as no stable groups of registrars, shortage of training opportunities, poor data quality, insufficient utilization and lack of multidisciplinary mechanisms, so that the cancer registration system still needs to be enhanced and improved. Along with the development of economy, science and information technology, methods and patterns of cancer registration is changing. It is to be expected that cancer registration will be automatic, nationwide and integrated with community healthcare in the near future.
